Add in a couple of scrappers and that's a perfectly fine 4/5 rotation. Marion can log time backing up both forward spots, and he's is savvy and big enough to play most 4s. If the opposition has an exceptionally big front court you can always use Haywood and Chandler a bit more.

Mavericks main objective should simply be to hold on to Chandler and Butler imo. Beaubois can take Barea's spot.

there is no way Bobo can take JJBs spot next season. He just broke his foot again. The dude looked awful running PG the last two years and only performed well when played at SG.

Terry is more likely to play PG than Bobo at this point.

KMart did imply at one point he wouldn't be opposed to playing in Dallas which was funny considering past history. I seriously doubt he would come to Dallas to be a low minute player on a small contract though.
